Linehu 7925c09677 feat: U4 ciphertext page dump tool 
- utrw/debug.c: utrw_debug_dump_page(slot,page,offset) — kernel debug-privileged dump of 64B ciphertext + decrypted plaintext hex to serial (PCKC key derive, no capability path)
- selftest demo: dump at offset 128 shows plaintext 'deshab utsm sealed memory selftest' vs unrelated ciphertext; SELFTEST PASS (.build_tmp/qemu_serial_u4dump.log)

Linehu 42fc06439c feat: R3b wire drr_emergency_pool_kb / drr_recovery_log_size from FUCK 
- drr_apply_config(pool_kb, log_size) before drr_init; pool_limit clamped to compile-time 64KB static pool (min sub-buffer layout enforced, defaults kept on bad values); recovery log size clamped to remaining pool
- verified in QEMU: pool_kb=32 -> pool_limit=0x8000, log_capacity=0x80, boot continues (.build_tmp/qemu_serial_r3b.log)

Linehu b76e8f1556 feat: U2 UTRW slow path real branches 
- slow_path.c: KEY_MISS -> PCKC re-derive (retry OK); EPOCH -> refresh cap epoch via out_cap (retry OK); STALE_CAP permanent; MAC_FAILED/POISONED -> PCKC invalidate + DRR fault report; RETRY passthrough
- status.h: add UTSM_ERR_MAC_FAILED (-11); utrw.h: slow path takes cap/rights/offset/len/reason + out_cap
- selftest: EPOCH refresh + KEY_MISS re-derive + POISONED passthrough coverage, full SELFTEST PASS in QEMU (.build_tmp/qemu_serial_u2slowpath.log)

Linehu 6e44fa5df7 feat: DEAICUP lotus panic screen + F2 fbcon abstraction 
- panic screen now draws embedded ohMyLogo.png (384px RGBA, gen_panic_logo.py); background color sampled from image corners so screen bg matches logo bg
- F2: include/utsm/fbcon.h unified framebuffer console (pixel/blend/fill/rgba-image/text with FBCON_HAVE_FONT opt-in); panic.c migrated onto it
- build.ps1 regenerates panic_logo_data.inc when ohMyLogo.png changes

Linehu e4307ff0ec feat: F1/F4/F5 phase-1 skeleton + insane-roadmap docs rework 
- docs: ROADMAP_INSANE (five-phase plan), TASKBOARD, STATUS single source of truth, PHILOSOPHY; rewrite README/ARCHITECTURE non-goals; archive ROADMAP phase 0-9; drop contradictory dev-plan doc
- F1: unified lotus panic screen (panic_full: fb draw + regs dump + DRR crash archive); IDT exception path and dkm_api_panic routed through it
- F4: leveled boot selftest (FUCK [boot] selftest=0|1|2), IDT/CS fatal checks + DMA probe
- F5: [dsk] skip_firstinit direct-to-desktop; build/configs dev+release templates now injected

LinehuandCursor 737a2cb0db fix: let nested-KVM vmlaunch succeed with Virtual NMIs 
Self-test and Linux guest were failing VM-instruction error 7. Share a KVM-style control adjust, request PIN_VIRTUAL_NMIS, and stop intercepting guest #PF. Land isolated XNU/Python/KDE scaffolding off the boot path.
